Keto Cauliflower Mashed Potatoes

Low Carb Cauliflower Mashed Potatoes

I’ve been making this keto mashed cauliflower since I started keto in 2012, and it’s the side dish I come back to more than any other. The reason mine tastes different from most cauliflower mash recipes is the cooking method. I steam the florets in chicken broth instead of boiling them in plain water. That broth infuses real flavor directly into the cauliflower, so you’re not starting from a bland, waterlogged base and trying to fix it with add-ins.

The squeeze step is where this recipe actually happens. After the cauliflower is fork-tender, I drain it, sandwich it between paper towels, and press out every drop of liquid I can. Skipping this is the single biggest reason cauliflower mash turns into soup. Reader after reader has confirmed the same thing in the comments below. Tricia put it perfectly: “The cream cheese can only do so much if the cauliflower is still waterlogged.”

Once the water is out, everything goes into a food processor with cream cheese, parmesan, salt, and pepper. The cream cheese makes it rich and thick, and the parmesan cuts any lingering cauliflower taste. I blend until it’s completely smooth, and what comes out looks, feels, and tastes like real mashed potatoes. I’ve served this at Thanksgiving and nobody clocked it. Reader Keisha’s husband, who grew up on Midwestern mashed potatoes, was halfway through the bowl before he asked what she did differently. That’s the kind of review that matters to me.

Here’s a tip nobody else mentions: if you want these to taste even more like real potatoes, try mashed potato extract. Start with one drop. Seriously, one. It’s incredibly strong and you can always add more. I mentioned this to a reader a couple years ago and it’s become one of my favorite tricks for skeptics.

This is one of my favorite low carb side dishes to pair with rich mains. I make it alongside keto green beans and bacon for weeknight dinners, or next to keto sweet potato casserole when I want a full holiday spread. It holds up as a base layer under keto cauliflower gratin too.

If you love cauliflower as much as I do, try my cauliflower tots, cauliflower fried rice, or air fryer cauliflower. And if you want another mashed side that isn’t cauliflower, my mashed turnips are worth trying.

I steam my cauliflower in a skillet with butter and homemade chicken broth instead of boiling it in water. The broth adds real flavor to the cauliflower from the start, so you’re not working against a bland base. I saute a couple garlic cloves in the butter first, then add the florets and broth and let it all simmer until a fork slides through easily (about 5-8 minutes).

Here’s the step that makes or breaks this recipe: squeeze out every drop of liquid before blending. I drain the cauliflower, sandwich it between paper towels, and press hard. You’ll be surprised how much water comes out. Skip this and you’ll end up with cauliflower soup, not mashed cauliflower. Two ounces of cream cheese cannot save waterlogged cauliflower. Once it’s dry, everything goes into the food processor with cream cheese, parmesan, salt, and pepper. Blend until smooth.
